We're doing the top end on Rommpy's 530 right now, 200+ hrs on it so we thought we would freshen up the top end. The valves had some carbon built up that needs removed, enter the ultrasonic cleaner. You don't want to use a wire brush etc to clean the carbon off since the valves have a factory coating on them that can be easily damaged. We dropped them in a Harbor Freight ultrasonic cleaner with some simple green and within a couple days the carbon was off the valves. You can get a great deal on the ultrasonic cleaner if you catch it on one of their sales...great for cleaning carbs etc.

Some pics....

Andy brought his cleaner over as well so we could speed things up a bit.




Valves out of the head






And out of the cleaner...no brushes etc needed.

Dang... that thing does a great job!





the top end needs a refresh at 200 hours? How many miles is that?

Wow ...
